INSTRUMENT FOR INSERTING CONTINUOUS BATS INTO UPHOLSTEBY P LAITS.

Application filed February 16, 1926. Serial No. 88,626.

or more sections or longitudinally splitv parts, between which the batting is threaded or drawn; when the operator uses such tools he is obliged to press the sections together, otherwise the continuous batting which is threaded through the instrument will pull out of the instrument when piping the plait of the cushion which causes the batting on the inside of the instrument to wrinkle the full length thereof and when the instrument is withdrawn the inserted batting does not fill the lait on account of the wrinkled condition. f the operator can not pound or pull the wrinkle out of the cotton batting in the plait, the cottonwill have to be taken out of the lait which means extra cost and loss of pro uction. My invention, therefore, seeks to avoid these objectional features and to that end I have produced the instrument comprising the subject matter of this invention.

Generically the invention comprises a long tubular body of proper cross sectional shape and of uniform cross section throughout that portion of its length which is insertable in the plait, the entrant end being provided, with a flare or funnel-like portion, while the exit end has provision for an operator to press his fingers or thumb on the bat to hold it while withdrawing the instrument; the instrument is also provided with bat grippers adjacent each end for the purpose of drawing the bat from the roll in which it'is wound (or from any other source) and for the purpose of holding the but while being severed, respectively. I

'More specifically the invention also lies in those novel combinations and arrangements of parts which will be hereinafter described and pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a side elevation showing the invention in use.

Figure 2 is a plan view of the same.

Figure 3 is an enlarged vertical longitudinal section of the instrument. parts being broken away showing in 11111 lines the bat gripper at the entrant end in operation.

Figure 4 is a view similar to Figure 3.

showing the bat gripper at the exit end in operation.

Figure 5 is an end elevation looking at the entraift end.

Figure 6 is an end elevation looking at the exit end.

In the drawings, in which like numerals of reference indicate like parts in all the figures, 1 is the table on which the upholstery to be stuffed is laidand on which the exit end of the instrument that constitutes my invention may rest. 2 is the stand on which the roll-3 of continuous bat is located for purposes of unwinding.

4 is the instrument which constitutes thesubject matter of my present invention. The instrument 4 consists of a section of tube or pipe of uniform cross section throughout that portion of its length which is adapted to be inserted into the plaits ofthe upholstery. At the entrant end thetube 4 has a flared or funnel-like port-ion 5 to facilitate the introduction of the bat and it is also slotted on the top as at 6 to cooperate with the bat gri per that serves to aid in un winding theliat from the roll 3. The gripper consists of a leaf spring 7 of a width to pass through the slots 6, one end 8 of the spring 7 being secured to the tube 4 by spot welding. brazing or in any other suitable way. The front end of the spring 7 is bent at right angles upwardly as at- 9 and then back upon itself as at 10 to constitute a convenient means by which the gripper 7 may be depressed into the slot 6'to grip the bat. as shown in Figure 1.

The front end 11 of the tube 4 is recessed top and bottom as at 15 and 16 respectively and the top is slotted as at 12 from the recess' inwardly a suitab'e distance. Lying over the slot 12 is a leaf spring 13, one end 14 of which is spot welded, brazed or otherwise permanently secured to the table 1. Normally the springs 7 and 13 lie parallel with their respective slots but do not project into the inner diameter of the tube.

17 is an eye secured to the entrant end of the tube by which it maybe suspended with a cable 18 from a suitable support 19 whereby the weight of the instrument is taken oil of the operator.

20 is the plaited upholstery to be stuiied. In using my invention the roll of continuous hat 3 is placedon the unwinding stand- 2 and has its end threaded through the in strument so that the end of the batwill project beyond the end of the spring 13 in order that when the instrument-is inserted its full limit into the bat the operator can press his. thumb on the plaiting adjacent the recessed or incut parts 16 and and hold the end of the bat while the tool is being withdrawn.

Before inserting the instrument into the plait pocket the operator grasps the instrument'adj acent the entrant end with his hand over the projection 10 of the gripper 7 and closes down on the grip r which forces it to the position shown in igure 1' and causes the bat to be firmly held there. Then as the instrument is advanced into the pocket the bat is unrolled correspondingly. In withdrawing the instrument from the pocket the operator, of course, releases pressure on the projection 10which permits the gripper 7 to restore itself to the inoperative position,

see Figure 4. As soon as the instrument has been withdrawn from the plait pocket the operator presses h1s thumb on the end of the spring gripper 13, thereby gripping the bat adjacent the exit end 11 of the instrument and by raising up on the instrument and holding down on the plait the section ofv the bat within the plait .is severed from the re-v mainder and the'instrument will then be sectional type 7 ready for insertion into the next plait pocket without wrinkling or twisting the batting.

from its normal state. The cross sectional shape of the instrument and its width and depth within, corresponds to the external shape and dimension of the bat and therefore the bat is not pressedor wrinkled as with instruments of the longitudinal split hereinbefore referred to. i From the foreg'oing description, taken in connection with the accompanying drawings,

it is thought the construction, operation and advantages of the invention will be clear to those skilled in the art to which it relates.
